Percent Error Worksheet
Periodic TableGrow CrystalsPhysics ProblemsMy Amazon StoreShop Calculate Percent Error 3 percent error definition Replies Percent error, sometimes referred to as percentage error, is an expression of the density and percent error worksheet difference between a measured value and the known or accepted value. It is often used in science to report the difference between experimental https://www.youtube.com/watch?v=BsIBxIomhNg values and expected values.The formula for calculating percent error is:Note: occasionally, it is useful to know if the error is positive or negative. If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine. For http://sciencenotes.org/calculate-percent-error/ example,, in experiments involving yields in chemical reactions, it is unlikely you will obtain more product than theoretically possible.Steps to calculate the percent error:Subtract the accepted value from the experimental value.Take the absolute value of step 1Divide that answer by the accepted value.Multiply that answer by 100 and add the % symbol to express the answer as a percentage.Now let's try an example problem.You are given a cube of pure copper. You measure the sides of the cube to find the volume and weigh it to find its mass. When you calculate the density using your measurements, you get 8.78 grams/cm3. Copper's accepted density is 8.96 g/cm3. What is your percent error?Solution: experimental value = 8.78 g/cm3 accepted value = 8.96 g/cm3Step 1: Subtract the accepted value from the experimental value.8.96 g/cm3 - 8.78 g/cm3 = -0.18 g/cm3Step 2: Take the absolute valu

The mass of the element is 10.23 g The volume of the water it was placed in was 20.0 mL The volume of the water after the element was placed in it was 21.5 mL b) If the accepted value how to calculate is 6.93 grams per milliliter, calculate the percent error in significant figures. 1 following 5 answers 5 Report Abuse Are you sure you want to delete this answer?

You're given a mass of 10.23 g, and based on the amount of displaced water the volume of the element is 1.5mL. So: 10.23/1.50 = 6.82g/mL. (6.82/6.93)*100=98.4% yield, or 1.6% error.

Take your estimate of what it should be, then subract the estimate from the actual number. divide this by the actual number, and multiply by 100. Doesn't matter if it's negative, just make it a
